Grabbing email from localhost node server for the moment

- Will obviously have to change this mail.tworgy.com + actually check the clients credentials
Added a simple options page

- Saves username/email/password. Password is not hashed and values are simply overridden in storage (no checking if already submitted details)
Removed legacy popup pages
Added TODO comment how should probably not blindly insert email into current input
Refactored out host + included readyState checks
Switched from using password to API key to identify user + auto grab if doesn’t have one
Show the changes if settings updated since page loaded

- Main case is when don’t have an API key to start off with, but then do once auto creating account occurs. Should normally happen well before options screen is loaded.

- Note: May be good idea to check API key exists and don’t allow options page to show until have an API key. Plus should have a manual grab API key button, as current code (i.e. background.js) only grabs API key first time extension is loaded.
